Northwest Africa Stone, ordinary chondrite, publication pending Western Sahara Find: 2007, TKW: ~10.8kg Individual 6,508g (inventory # B-230) Individual in the shape of a hammerhead with a flat base. The meteorite shows a couple of well defined regmaglypts on three of the six surfaces. Despite moderate weathering it displays a number of sections with pronounced flowlines, especially at the fringes of the regmaglypts. The specimen consists of two fragments, 5652.80g and 855.20g respectively. Both fragments were found close to each other, the meteorite most probably fragmented on impact. Detail of the fusion crust showing contraction cracks and traces of light weathering and mechanical abrasion through sand. The fitting surfaces of the two fragments display an unbrecciated and moderately equilibrated matrix with a relatively high iron content suggesting a H(5) type ordinary chondrite. Note the single chondrule in the lower center of the image. Regmaglypt in detail, carved out of the rock by the plasma jet stream during the athmospheric passage. Meteorites of this size and character have become rare even in the deserts of North Africa. Statistically a prospector will have to find several hundred individual masses before he comes upon a mass this size. NMR scale cube has 1cm.
